Effect of corner on evacuation behaviour during building egress by using dem-based multi agent model / Nur Hanis Kasehyani
Tesis ini tertumpu kepada kajian mengenai kesan penjuru kepada kelakuan pemindahan semasa keluar dari bangunan. Kajian kes telah dijalankan di Pusat Pengajian Kejuruteran Awam (PPKA). Objektif kajian ini adalah untuk menentukan kapasiti penjuru, mencari ketumpatan nilai ambang berhampiran penjuru semasa pemindahan keluar dari bangunan dan menentukan lebar kritikal yang berkaitan dengan bilangan pejalan kaki yang berbeza. Simulasi andaian suasana pemindahan di penjuru dijalankan dengan bilangan pejalan kaki yang berbeza dan lebar penjuru yang berbeza. Had kajian ini adalah bilangan pejalan kaki dan lebar penjuru. Sejumlah 27 simulasi telah dianalisis menggunakan domain cubaan yang dicadangkan berdasarkan lebar yang berbeza (1.50m, 2.25m dan 3.00m) dan bilangan pejalan kaki yang berbeza (60,65,70,75,80,85,90,95 and 100). Simulator ‘Crowd Behaviour Simulator for Disaster Evacuation (CBS-DE)’ dengan penambahan alat bantuan dipanggil ‘Human Behaviour Simulator (HBS)’ digunakan untuk menganalisa kelakuan pemindahan. Hasil yang diperolehi daripada simulasi tersebut adalah masa yang diambil untuk keluar dan daya interaksi. Hasil kajian menunjukkan tiada kesesakan dan penyumbatan yang menunjukkan ketumpatan nilai ambang kerana bilangan pejalan kaki tidak cukup untuk menghasilkan kesesakan dan penyumbatan. Di samping itu, Inter 9 menunjukkan graf siri masa untuk maximum daya interaksi yang terbaik kerana menunjukkan peningkatan nilai daya interaksi jika berlaku penurunan lebar penjuru dan nilai maximum daya interaksi tidak melebihi had daya interaksi. Kajian kes menunjukkan dengan mengkaji jalan keluar alternatif dapat meningkatkan kecekapan proses pemindahan keluar di tingkat bawah PPKA. _______________________________________________________________________________________________________ This thesis focuses on the effect of corner on evacuation behavior during building egress. The case study is conducted at Pusat Pengajian Kejuruteraan Awam (PPKA). The objectives of this study were to quantify the capacity of corner, determine numerically the threshold density near the corner during building egress and determine the critical width related to different density of pedestrian. Simulation of hypothetical evacuation scenarios at corner was carried out based on different pedestrian density and different widths. The main parameters of this study are the pedestrian density and width of corner. A total of 27 simulations had been performed on the trial domain with three different width and nine different pedestrian density. Crowd Behavior Simulator for Disaster Evacuation (CBS-DE) with the additional tool called Human Behavior Simulator (HBS) was used to analyze the evacuation behavior. The results of the simulations were egress time and interaction force. The findings show that there are no series of jamming and clogging that indicate the threshold density since the pedestrian density may be not sufficient to cause jamming and clogging. Meanwhile, Inter-9 shows the best time series of the maximum interaction force graph with pattern of increasing maximum interaction force as the corridor width decreases and the interaction force did not exceed the upper and lower limit of contact force. From the case study, it is found that the alternative evacuation route can improve the evacuation process at the ground floor of PPKA.
